DETAILED DESCRIPTION OF THE SEVERAL EMBODIMENTS

Hereinafter, the present disclosure will be further described with reference to the accompanying drawings. However, the present disclosure is not limited to the following embodiments.

FIGS. 1-24 shows a specific example of an electric seesaw swing. This example is the electric seesaw swing, which includes a upright post 1. A motor 2 is mounted on a top portion of the upright post 1, and a rocker 3 is connected to a rotating shaft of the motor 2. And the electric seesaw swing further includes a left swinging rod 4 and a right swinging rod 5. An end of the left swinging rod 4 and an end of the right swinging rod 5 are hinged to a free end of the rocker 3. A left top frame 6 and a right top frame 7 are respectively connected at a left end and a right end of the top portion of the upright post 1 and form a T-shaped structure together with the upright post. An end of the left top frame 6 is hinged with two first upper frame rods 8, and an end of the right top frame 7 is hinged with two second upper frame rods 9. A first hanging rod 10 is inserted between bottom ends of the two first upper frame rods 8, and a second hanging rod 11 is inserted between bottom ends of the two second upper frame rods 9. The first hanging rod 10 and the second hanging rod 11 are respectively hinged with a first inner frame rod 12 and a second inner frame rod 13. An upper end of the first inner frame rod 12 and an upper end of the second inner frame rod 13 are respectively hinged on the end of the left top frame 6 and the end of the right top frame 7. Another end of the left swinging rod 4 and another end of the right swing rod 5 are respectively connected to the first inner frame rod 12 and the second inner frame rod 13. Two left lower frame rods are hinged on a front end and a rear end of the first hanging rod 10 respectively. Two right lower frame rods are hinged on a front end and a rear end of the second hanging rod 11 respectively. A seat 15 is connected between bottom ends of the left lower frame rods as well as between bottom ends of the right lower frame rods respectively. Hinged portions of the first hanging rod 10 on which the two first upper frame rods 8, the first inner frame rod 12 and the left lower frame rods 14 are hinged, as well as hinged portions of the second hanging rod 11 on which the two second upper frame rods 9, the second inner frame rod 13 and the right lower frame rods are hinged, are inserted with locking mechanisms respectively, such that the hinged portions of both the first hanging rod 10 and the second hanging rod 11 are locked.

Both the first inner frame rod 12 and the second inner frame rod 13 each have a Y-shaped structure that is stable. Two bifurcated ends (i.e., two first bifurcated ends) of the first inner frame rod 12 are hinged on the first hanging rod 10, and the upper end of the first inner frame rod 12 is hinged to the end of the left top frame 6. Two bifurcated ends (i.e., two second bifurcated ends) of the second inner frame rod 13 are hinged to the second hanging rod 11, and the upper end of the second inner frame rod 13 is hinged to the end of the right top frame 7.

The locking mechanism includes plugs 30 each with a polygonal cross-section, and the plug 30 with the polygonal cross-section may be used to efficiently lock. A rear end of the plug 30 is connected with a handle portion for easy manual insertion and extraction. A front end of the plug 30 is opened with a mounting hole 16, and a locking screw 17 may be inserted into the mounting hole 16. The hinged portions of the first hanging rod 10 on which the first upper frame rods 8, the first inner frame rod 12 and the left lower frame rods 14 are hinged, and the hinged portions of the second hanging rod 11 on which the second upper frame rods 9, the second inner frame rod 13 and the right lower frame rods are hinged are formed with slots. The plugs 30 pass through the slots respectively, and the plug is locked and fixed by the locking screw 17. And thus the structure is simple, and the locking manner is convenient.

The first hanging rod 10 is provided with two plugs 30. One slot, which is formed by the bottom end of the first upper frame rod 8, a top end of the left lower frame rod 14, and the bifurcated end of the first inner frame rod 12 which are all at the front end of the first hanging rod, is inserted with one plug 30. One slot, which is formed by the bottom end of the first upper frame rod 8, a top end of another left lower frame rod 14, and another bifurcated end of the first inner frame rod 12 which are all at the rear end of the first hanging rod, is inserted with another plug 30.

The second hanging rod 11 is provided with other two plugs 30. One slot, which is formed by the bottom end of the second upper frame rod 9, a top end of the right lower frame rod, and the bifurcated end of the second inner frame rod 13 which are all at the front end of the second hanging rod 11, is inserted with one plug 30. One slot, which is formed by another bottom end of another second upper frame rod 9, a top end of another right lower frame rod, and another bifurcated end of the second inner frame rod 13 which are all at the rear end of the second hanging rod 11, is inserted with another plug 30. Springs 22 are connected between the left top frame 6 and the left end of the top portion of the upright post 1 as well as between the right top frame 7 and the right end of the top portion of the upright post 1, respectively. Bolts 23 are connected between the left top frame 6 and the left end of the top portion of the upright post 1 as well as between the right top frame 7 and the right end of the top portion of the upright post 1 and the bolts 23 are inserted into the springs 22 respectively.

The principle is as follows. A linkage movement mechanism includes the rocker 3, the left swinging rod 4, the right swinging rod 5, the first upper frame rods 8, the second upper frame rods 9, the first hanging rod 10, the second hanging rod 11, the first inner frame rod 12, the second inner frame rod 13, the left lower frame rods 14, the right lower frame rods, and seats 15. Under being driven by the motor 2, the rocker 3 is rotated around the motor, connection ends of both the left swinging rod 4 and the right swinging rod 5 which are connected with the rocker 3 are rotated around the motor along with the swinging of rocker 3, and distal ends of both the left swinging rod 4 and the right swinging rod 5 are connected with the first inner frame rod 12 and the second inner frame rod 13 respectively. In this way, the first inner frame rod 12 and the second inner frame rod 13 are swung from side to side. The first hanging rod 10 of the disclosure is configured to connect the first upper frame rods 8 and the left lower frame rods 14. A pair of locking mechanisms are provided at two ends of the first hanging rod 10, and the locking mechanisms includes plugs 30 each with the polygonal cross-section. A rear end of the plug 30 is connected with a handle portion, and a front end of the plug 30 is opened with the mounting hole 16. The locking screw 17 is inserted into the mounting hole 16. The hinged portions of the first hanging rod 10 on which the first upper frame rods 8, the first inner frame rod 12 and the left lower frame rods 14 are hinged, and the hinged portions of the second hanging rod 11 on which the second upper frame rods 9, the second inner frame rod 13 and the right lower frame rods are hinged are formed with slots. The plugs 30 pass through the slots respectively, and the plug is locked and fixed by the locking screw 17. When the plugs 30 are in the inserted state, the first hanging rod 10 and the left lower frame rods 14 and/or the second upper frame rods 9 and the right lower frame rods are in a locked connection state, the first hanging rod 10 and the left lower frame rods 14 are moved consistently as a whole, or the second upper frame rods 9 and the right lower frame rods are moved as a whole, which is in the A mode as shown in FIGS. 3-11.

When the plugs 30 are in the pulled-out state, the left and right lower frame rods may be rotated around the respective hanging rods, and the swing is in “B mode” at this time. Except for the left and right lower frame rods and the seats 15, the other parts have the above-mentioned movement characteristics of “A mode”. The B mode also has the movement characteristics different from the A mode as follows. First, when the motor 2 does not provide power and the plugs 30 are in the unlocked state, the left and right lower frame rods can swing independently, and the movement mode is the same as that of a normal swing. Second, when the motor 2 rotates to drive and the single-sided plugs 30 are in the pulled-out state, the lower frame rods from which the plugs 30 are not pulled out are moved in the aforementioned “A mode” movement mode, the upper frame rods and the hanging rod from which the plugs are pulled out are swung in the same manner as that of the aforementioned “A mode”. And the lower frame rods and the seats 15 connected with both upper frame rods and the hanging rod, from which the plugs are pulled out, also have an additional rotational movement around this hanging rod under an action of the gravity. Third, when all the plugs 30 are in the pulled-out state, the upper frame rods and the hanging rods at two sides are swung in the same manner as that of aforementioned “A mode”, and the left and right lower frame rods and the seats 15 connected to them also have additional rotational movements around the respective hanging rod under the action of the gravity.

In a premise where the swing is in the motion states of the A mode and the B mode, the connection between the left top frame 6 and the left end of the top portion of the upright post 1 as well as the connection between the right top frame 7 and the right end of the top portion of the upright post 1 are realized by the bolts 23. When unlocking the bolts 23 to the upright post 1 as well as the left top frame 6 or the right top frame 7, the upright post 1 as well as the left top frame 6 or the right top frame 7 will be connected by the springs 22. With the elastic connection of the springs 22, the left top frame 6 and the right top frame 7 are swung up and down to a certain extent, and the swing is in “C mode” at this time, which will has the movement characteristics as follows. First, the left top frame 6 and the right top frame 7 are at the top portion of the motor cover 24 and have characteristics of a seesaw at under the action of the springs 22. And this form of movement is transmitted to the seats 15 at two sides through the connection of the left top frame 6 and the right top frame 7. Second, the left top frame 6 and the right top frame 7 are swung from side to side in combination with the movement characteristics of “A mode”. Third, the left top frame 6 and the right top frame 7 are swung from side to side in combination with the motion characteristics of “B mode”.

In addition to adopt the format of rigid material parts, the left and right lower frame rods in this disclosure may also be replaced with flexible ropes, which will have more possibilities in the way of movement. The rocker 3, the left swinging rod 4, and the right swinging rod 5, in addition to the mid-mounted connection as shown in figures, can also be connected by connection links on two sides of the seat 15. In addition to the structure in the figures, the upright post 1 may also have a variety of structures. The base of the upright post 1 may be added a motor to rotates, so as to achieve more forms of movements. The motor cover 24 may also be integrated into the upright post 1 as a part. The top portion of the motor cover 24 may support the left and right top frames by an open-type connection such as raised reinforcing ribs, or a semi-open or semi-closed connection such as grooves, shafts and the like.

The present disclosure has a variety of usage manners, which may specifically include the following modes.

In a first usage manner referred briefly to as A mode, as shown in FIG. 13, the plugs 30 are in a inserted state, and the first hanging rod 10, the first inner frame rod 12 and the left lower frame rods 14 are all in a locked connection state, and these parts are moved consistently as a whole. The following describes the movement characteristics of the linkage movement mechanism in A mode. In a case where the rocker 3 starts to rotate in a clockwise direction from a vertical downward state, first, as shown in FIGS. 3-5 and 11, when the distal end of the rocker 3 rotates at a position lower than a connecting axis point of the motor 2, the movement directions and the speeds of both the first hanging rod 10 and the second hanging rod 11 are the same, in a range from a position of the rocker 3 and the left swinging rod 4 in a line to a position of the rocker 3 and the right swinging lever 5 in a line; second, as shown in FIGS. 5 and 6, while the rocker 3 rotates in a clockwise direction from a position that the rocker 3 and the left swinging rod 4 are in a line to a position that the rocker 3 and the right swinging rod 5 are overlapped, a movement direction of the first upper frame rods 8, the first hanging rod 10, the left lower frame rods 14 and the seat 15 is represented by D, and a movement direction of the second upper frame rods 9, the second hanging rod 11, the second inner frame rod 13, the right lower frame rods and the seat 15 is represented by E opposite to D, a frame group including the first upper frame rods 8 is swung to a right and a frame group including the second upper frame rods 9 is swung to a left; third, as shown in FIGS. 6-8, while the rocker 3 is rotated in a clockwise direction from a position that the rocker 3 and the right swinging rod 5 are overlapped to a position that the rocker 3 is in a vertical state, the frame group including the first upper frame rods 8 and the frame group including the second upper frame rods 9 are both swung to a right, and a swinging speed of the frame group including the first upper frame rods 8 is greater than that of the frame group including the second upper frame rods 9; fourth, as shown in FIGS. 8-10, while the rocker 3 is rotated clockwise from a position that the rocker 3 is in the vertical state to a position that the rocker 3 and the left swinging rod 5 are overlapped, the frame group including the first upper frame rods 8 and the frame group including the second upper frame rods 9 are both swung to a right, and a swinging speed of the frame group including the second upper frame rods 9 is greater than that of the frame group including the first upper frame rods 8; fifth, as shown in FIGS. 10-11, while the rocker 3 is rotated clockwise from the position that the rocker 3 and the left swinging rod 4 are overlapped to a position that the rocker 3 and the right swinging rod 5 are in a line, the movement directions of both the frame group including the first upper frame rods 8 and the frame group including the second upper frame rods 9 are opposite, i.e., the frame group including the first upper frame rods 8 is swung to the left, and the frame group including the second upper frame rods 9 is swung to the right; sixth, if the rocker 3 rotates counterclockwise, the movement principle for the rocker is the same as above, and connecting parts thereof are moved in a reverse direction along with the rocker.

In a second usage manner referred briefly to as B mode, as shown in FIG. 12, the plugs 30 are pulled out, the left and right lower frame rods may rotate around the hanging rods (i.e., the first hanging rod 10 and the second hanging rod 11), and other parts have the movement characteristics of above-mentioned “A mode” except for the lower frame rods and the seats 15. The B mode also has the movement characteristics different from the A mode as follows. First, as shown in FIGS. 12 and 14, when the motor 2 does not provide the power and the plugs 30 are pulled out, the left and right lower frame rods 14 may be swung independently, which may be used as the ordinary swing. Second, when the motor 2 rotates to drive and only the left or right plugs 30 are in the inserted state, the lower frame rods that are not inserted with the plugs moves in the aforementioned “A-mode” motion mode, the hanging rod (i.e., the first hanging rod 10 or the second hanging rod 11) that is inserted with the plugs 30 has a same swing mode as the aforementioned “A-mode”, and the lower frame rods connected to this hanging rod have an additional rotation movement around this hanging rod (i.e., the first hanging rod 10 or the second hanging rod 11) under the action of gravity, as shown in FIG. 15. Third, when the left and right plugs 30 are in the unlocked state, the hanging rods on both sides (i.e., the first hanging rod 10 and the second hanging rod 11) have the same swinging mode as the aforementioned “A mode”, and the lower frame rods connected with these hanging rods have additional rotation movements around these hanging rods (i.e., the first hanging rod 10 and the second hanging rod 11), as shown in FIG. 16.

In a third usage manner referred briefly to as C mode, as shown in FIGS. 17 to 19, the bolts 23 is released from the connection between the upright post 1 and the left top frame 6, as well as between the upright post 1 and the right top frame 7. At this time, the upright post 1 and the left top frame 6 as well as the upright post 1 and the right top frame 7 will be connected by the springs 22. As shown in FIGS. 1 and 2, because the raised reinforcement rib on the top of the motor cover 24 is in contact with the inner sides of the arc-shaped rods for support, the left top frame 6 and the right top frame 7 will be swung around the reinforcement rib at the top of the motor cover 24 under the elastic connection of the springs 22, thereby realizing the function of the seesaw, i.e., the C mode of the present disclosure. The swing in the C mode has the movement characteristics as follows. First, the left top frame 6 and the right top frame 7 have the characteristics of the seesaw under the action of the raised reinforcement rib on the top of the motor cover 24 and the springs 22, and this form of movement is transmitted to the seats 15 on two sides through the hangers. Second, as shown in FIG. 20, the left top frame 6 and the right top frame 7 are swung from side to side in combination with the movement characteristics of “A mode”. Third, as shown in FIGS. 21 to 24, the left top frame 6 and the right top frame 7 are swung from side to side in combination with the movement characteristics of “B mode”.

As an improved example, the top portion of the upright post 1 is vertically connected with a plurality of support posts 18. Top portions of some of the support posts 18 are connected to a first top plate 19 for support, and top positions of the remaining support posts 18 are connected to a second top plate 20 for support. There is a gap 21 between the first top plate 19 and the second top plate 20. The motor 2 is installed on the first top plate 19. The rocker 3 is located in the gap 21 and can be swung in the gap 21 along with the rotation of the motor 2. So, the structure is simple. Furthermore, the rocker 3 is in the middle position, which is convenient for a concealed installation, and does not affect the rocker 3 to swing.

As an improved example, the electric seesaw swing also includes an arc-shaped motor cover 24. The motor cover 24 is arranged outside the motor and connected to the first top plate 19 and the second top plate 20.
